Built around the large 50 mm\/40 mm pipe class, it minimises friction at these volumes for maximum throughput.\u003c\/p\u003e \u003cp\u003eAt 10 m suction output reaches 170 L\/Min — the single highest figure across every CJ injector configuration — with head topping out at 53 m. The 2.4 kW \/ 240V motor draws 14.1 Amps, supporting demanding high-volume transfer duties where throughput is essential.\u003c\/p\u003e \u003cp\u003eThe injector sits down the bore, keeping moving parts and electricity above ground. Thermoplastic injector resists salt, hardness and iron. At 170 L\/Min, the smooth internal bore keeps turbulence low. The jet and venturi are matched to bore yield. An optional Offset Flange (101431, 1½ x 1½ inch female thread) allows installation away from the bore to access water above flood level or closer to electricity.\u003c\/p\u003e \u003cp\u003eThe pump features a cast iron body, stainless steel shaft, double race bearings and a carbon ceramic mechanical seal. The TEFC motor includes thermal overload protection and handles liquid temperatures up to 65°C. Supplied with the dedicated WK-CJ850 water kit assembled and glued, including a 60 litre tank with 20 litre draw-off. A 2-year warranty applies; loss-of-prime switch optional.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDW79-20 injector with 50 mm suction and 40 mm discharge pipework.\u003c\/li\u003e \u003cli\u003eThermoplastic injector tolerates salt, hard water and iron.\u003c\/li\u003e \u003cli\u003eSmooth injector bore reduces turbulence at maximum flow.\u003c\/li\u003e \u003cli\u003eNo moving parts or electricity down the bore.\u003c\/li\u003e \u003cli\u003eJet and venturi matched to available groundwater yield.\u003c\/li\u003e \u003cli\u003eCast iron pump body with stainless steel motor shaft.\u003c\/li\u003e \u003cli\u003eDouble race bearings with carbon ceramic mechanical seal.\u003c\/li\u003e \u003cli\u003eTEFC motor with thermal overload protection.\u003c\/li\u003e \u003cli\u003eSuitable for liquid temperatures up to 65°C.\u003c\/li\u003e \u003cli\u003eWK-CJ850 water kit supplied assembled and glued.\u003c\/li\u003e \u003cli\u003eIncludes pressure gauge, brass 5-way tee, gate valve and stainless steel barrel union.\u003c\/li\u003e \u003cli\u003e60 litre tank with 20 litre draw-off and 30-50 psi switch setting.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Orange Pumps","offers":[{"title":"Default Title","offer_id":50962917687543,"sku":"CJ850-1P-DW79-20","price":2346.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/orange-pumps-cj850-dw79-20-bulk-transfer-deep-well-jet-pump-tank-filling-venturi.png?v=1784798233","url":"https:\/\/foundationpumps.com.au\/products\/orange-pumps-cj850-dw79-20-bulk-transfer-deep-well-jet-pump-tank-filling-venturi","provider":"Foundation Pumps","version":"1.0","type":"link"}
